v6 XR4x4 is different bellhousing same internals
2.0DOHC Xr4x4 will fit (and 4x4 ghia saphs)
i know the v6 / cossie ratios are the same, dunno about 2.0 / cossie tho i THINK its only the diff thats different but that woud need confirming with sum1 cleverer than me...
strengthwise they all the bloody same tho... just pay more for something with "cosworth" on the nametag tho
